Automation, Text Data Files
Note: Objects must created before they are referred to later in the file. So a new line type must be created
in the data file before a line can be later modified to refer to it.
Data found on the General And Environment Data forms
Data on these forms can be set by referencing the General or Environment objects as follows (the following example
assumes that the base file model has 2 simulation stages):
General:
ImplicitUseVariableTimeStep: Yes
ImplicitVariableMaxTimeStep: 0.2
# Add another simulation stage
NumberOfStages: 3
StageDuration[3]: 12.0
Environment:
SeaBedStiffness: 3000
SeaBedDamping: 80
RefCurrentSpeed: 1.2
RefCurrentDirection: 36.0
Wave train data requires that the target wave train is selected by name first. The example assumes a base file model
with only one wave train and adds a new wave train and names it 'AiryWave' (after being added the wave train is
automatically selected). Then the first wave train is modified after being selected with the SelectedWave
identifier:
Environment:
# Add a wave train
NumberOfWaveTrains: 2
WaveName[2]: AiryWave
# AiryWave is now the selected wave
WaveType: Single Airy
WaveDirection: 180
WaveHeight: 3.2
WavePeriod: 12.5
# Change selected wave to Wave1
SelectedWave: Wave1
WaveDirection: 100
WaveHeight: 4.3
WavePeriod: 7.8
Data for Multiple Current data sets
The example below creates two Currents in a multiple current set, and selects one to be the active current using the
ActiveCurrent identifier:
Environment:
# Multiple current set
MultipleCurrentDataCanBeDefined: Yes
NumberOfCurrentDataSets: 2
CurrentName[1]: Ebb
CurrentName[2]: Flow
# To modify the Ebb current, we must select it first
